It is rumoured that Farrell will be joined by a female co-star, though Nic Pizzolatto confirmed that the show will feature four lead roles.

Matthew McConaghuey and Woody Harrelson in the first season of True Detective.

"They didn't exist until I created them, then in their creation I developed a personal attachment to them," Pizzolatto said of his new characters.

"I think it's the same in anything you write. It's your job to come up with compelling characters who speak to an individual authenticity. If I'm not interested in the characters I can't go on. I have to be fascinated by them. It's the same job as Season 1 to me."
